So I am 17 weeks long and I was sitting on my couch rubbing my belly. pretty low down like between my hips on the right side I feel like this really hard lump and when I feel on the other side it is more squishy. Could this lump be the baby sitting really far forward or should I be conserned that it is something else? Now going back and feeling in that same area I do not feel the lump. What are your thoughts?
